Alphonse Bellier (21 July 1886 – 1 November 1980) was a French auctioneer specializing in the sale of art collections.
The son of a baker from Saint-Nazaire, Alphonse Louis Marie Bellier came to Paris in 1918 and began his career as a notary, before becoming an auctioneer on 27 March 1920.
His main place of work was the Hôtel Drouot, where he conducted a large number of art sales.
He surrounded himself with experts such as Jos Hessel, André Schoeller (1879-1955), Jacques Mathey and Robert Lebel, for sales of paintings and drawings.
During the Occupation, Bellier organized over 250 sales for the Hôtel Drouot auction house between 1941 and 1944.
